J 10 CFR Part 70.23, specifically relating to the requirement that the proposed equipment and facilities are adequate'to protect health and minimize danger to life or property.
10 CFR Part 70.61(e), specifically relating to the requirement that each engineered or administrative control or control system that is needed to meet the performance requirements be designated as an item relied on for safety.
10 CFR Part 70.62, specifically relating to the establishment and maintenance of a safety program and to the conductance of as ISA.
10 CFR Part 70.64, specifically relating to the application of BDCs and defense-in-depth practices to new facilities or new processes at existing facilities.
12.4.3.2 Regulatory Guidance.
None, at present, specific to 10 CFR 70 licensees
'12.4.3.3 Regulatory Acceptance Criteria The reviewer will determine that the applicant's cooling water system is acceptable if it satisfies the relevant requirements listed in Section 12.4.3.1 and follows these guidelines:
a.
The system description and theory demonstrates how the cooling water system and its subsystems transfer heat loads from safety-related structures, systems, and components to an appropriate heat sink under both normal operating and accident conditions.
b.
The description demonstrates an adequate water supply under normal and hazardous conditions c.
The description demonstrates adequate component redundancy and the capability to isolate components, systems or piping for maintaining system safety function under varying system configuration, and the capability of integrated system control.
d.
Management measures including tests and other verification methods that demonstrate the structural integrity and system leak tightness, the operability and adequate performance of active system components, and the capability of the system to perform required functions during normal, and accident situations.
e.
Descriptions of the system showing the capability for withstanding environmental hazards resulting from pipe line breaks and dynamic effects associated with flow instability and attendant loads such as water hammer, or cavitation, and measures to prevent such dynamic conditions from occurring.
l
l f.
Design features which include capacity and capability for detecting leakage of
' radioactivity, chemical contamination from one system to another, and allowing inservice component inspection, system maintenance, and operational functional testing of the system and its components.

10 CFR Part 70.22, specifically relating to the requirement that the applicant is to provide a description of the equipment and facilities and propose procedures to protect health and minimize danger to life and property.
10 CFR Part 70.23, specifically relating to the requirement that the Commission determine that the proposed equipment, facilities, and procedures are adequate to protect health and minimize danger to lifa and property.
10 CFR Part 70.61(e), specifically relating to the requirement that each engineered or administrative control or control system that is needed to meet the performance requirements be designated as an item relied on for safety, 10 CFR Part 70.62,'specifically relating to the establishment and maintenance of a safety 1

J 10 CFR Part 70.64, specifically relating to the application of BDCs and defense-in-depth practices to new facilities or new processes at existing facilities.
12.4.1.2 Regulatory Guidance The NRC regulatory guides and industry standards applicable to the ventilation system that in general provide guidance for implementing and satisfying the regulatory requirements and acceptance criteria are: NRC guidance documents such as NUREG -0800 " Standard Review Plan" and Regulatory Guide 3.12 " General Design Guide For Ventilation Systems of Plutonium Processing and Fuel Fabrication Plants"; DOE Standard 3020, " Specification for HEPA Filters Used by DOE Contractors"; and and industry codes and standards issued by the American National Standards Institute, American Society of Mechanical Engineers, Air Movement and control Association, American Society of Heating, Refrigerating and Air-Conditioning Engineers, and Sheet Metal, and Air Conditioning Contractors National Association, National Fire Protection Association, and Underwriters Laboratories.
12.4.1.3 Regulatory Acceptance Criteria The applicant's ventilation system design and operation are acceptable if they satisfy the relevant requirements listed in Section 12.4.1.1 and follow the relevant guidelines mentioned under Section 12.4.1.2. Relevant requirements and guidelines for ventilation systems are those related to the applicable BDCs (quality standards and records; environmental and dynamic effects; utility service; inspection, testing and maintenance; and instrumentation and control) and defense-in-depth. Typically, these specific design considerations include:
1.
Confinement of radioactive contamination by zones and pressure differentials 2.
Test, calibration, and in-service surveillance capabilities I
.....i
i i
3.
Redundancy of fans, dampers, and power supplies
- 4.
No single failure vulnerability S.
Sufficient capacity and capability 6.
Interlocks on supply fans to prevent zone pressurization 7.
Status monitoring and alarms 4
8.
Proper equipment qualification, quality assurance, and reliability.
9.
Adequate design for natural phenomena
- 10.
Appropriate fire protection and smoke control 11.
Continuous monitoring of recirculated air to occupied areas and diversion of contaminated air to a once-through exhaust system if allowable radiation standards are exceeded.
I 12.
Removal and replacement of filters is designed to permit only minimum exposure of personnel to radioactivity.
Additionally, the ventilation system design and operation should fulfill the functional requirements determined from the ISA and the system shot, d be available and reliable to perform its intended safety function when needed.
